The Alpinestars Supertech helmet family was designed with a clear objective: to create the most advanced, protective, and high-performance helmets for riders worldwide. With the S-M10, Alpinestars engineers developed a helmet that combines exceptional ventilation, unparalleled comfort, and extreme lightness, without compromising safety. Its streamlined aerodynamic design minimizes pressure points and the risk of snagging in the event of an impact, while optimizing energy distribution and dissipation for maximum protection of the head, neck, and spine. The S-M10 helmet thus represents the absolute benchmark in technology, safety, and performance in the world of motocross and off-road riding.

The solution chosen for calculating the shell size of the S-M10 ensures that each helmet size has its own shell size, providing the most ergonomic solution to meet the diverse fit requirements worldwide. Four different helmet shell sizes (S, M, L, and XL) and six general sizes (XS to XXL) are offered to guarantee motorcyclists a proper fit that not only improves comfort and reduces overall weight, but also, and most importantly, enhances the helmet's impact performance.

The patented A-Head Fitment System allows for easy adjustment of the helmet's angle and height on the head.

This ultra-ventilated helmet features 28 individual intake and exhaust vents, excluding the eye vent, with 18 intake vents and 10 exhaust vents for optimal airflow.
